Sash balancer for a Millard window

Hi there- thanks for posting! 

I was able to narrow what you have down to two options. You either have our Series 380 or our Series 385 channel balance. The difference lies in the depth of the shoe. The series 385 balance has a 15-004 shoe, which is 1-3/32” deep while the Series 380 balance has a 15-005 shoe, which is 1” deep.

Please reference the below photo to see exactly how to measure the depth of your shoe to determine which series you have.

Once you decide which Series balance you have, you will select the 25" length in that series and choose the 2040 stamp "option". 

If you have any questions at all please don’t hesitate to reach out to us.
